A total of 63 arrests – one fifth of them for felonies – were made and 182 summonses issued in city schools over a span of 50 school days between July and September, according to the data, which the New York Civil Liberties Union published on its website. Most of the quarterly reporting period took place during the summer session, when enrollment is just 10 percent of the school-year total. Arrest totals are likely to be much higher when school is in session full time.

More than a third of the students arrested — 22 — were charged with assault, and more than half of summonses issued were for disorderly conduct. Riding a bike on the sidewalk was the second most common reason cited when issuing a summons, which typically requires a student to take time off of school to appear in court.

More than 80 percent of students arrested were male and 44 percent were younger than 16. All but four of the students arrested were black or Latino.

“The data raise concerns about black students being disproportionally arrested in the city’s schools,” said Donna Lieberman, executive director of the New York Civil Liberties Union.

DOE data released earlier this month showed that 83 percent of suspensions last year were issued to black and Hispanic students, who make up about 70 percent of students in the city schools.

Both the suspension and arrest data were released under the terms of the Student Safety Act, a law the City Council passed last year to require transparency about discipline in city schools. Since 1998, NYPD has been authorized to provide law enforcement inside city schools, but the department’s repeatedly refusals to release arrest information to the public led civil rights groups, including the NYCLU, to push for the Student Safety Act.

Earlier this month, the DOE held up its end of the act’s compliance requirements by releasing the suspension data, but the NYCLU accused the NYPD of stonewalling. Today, the group questioned whether the new data represented a complete accounting of arrests since the statistics account only for arrests made by school safety officers and omit arrests made by other police officers who are called in to schools. In addition, the NYPD did not release a required race breakdown for the summonses issued.

Udi Ofer, the NYCLU’s advocacy director, said the new data renewed questions about the city’s approach to student discipline.

“Instead of arresting students who need the most help, the Bloomberg administration should redirect resources from police to services that support student achievement,” Ofer said in a statement. “Why are we employing 5,400 police personnel [in schools] and only 3,000 guidance counselors?”

Labor Day used to signal the end of summer break and the return to school. That’s no longer the case in Tennessee, but the long holiday is a good time to catch up on all that happened over the summer. Here are 10 stories to get you up to speed on K-12 education in Tennessee and its largest school district.

TNReady is back — with a new test maker.

Last school year ended on a cliffhanger, with the State Department of Education canceling its end-of-year tests for grades 3-8 in the spring and firing testmaker Measurement Inc. after a series of missteps. In July, Commissioner Candice McQueen announced that Minnesota-based Questar will pick up where Measurement Inc. left off. She also outlined the state’s game plan for standardized tests in the coming year.

But fallout over the state’s failed TNReady test in 2015-16 will be felt for years.

The one-year void in standardized test scores has hit Tennessee at the heart of its accountability system, leaving the state digging for other ways to assess whether all of its students are improving.

Speaking of accountability, Tennessee also is updating that plan under a new federal education law.

The state Department of Education has been working with educators, policymakers and community members on new ways to evaluate schools in answer to the federal Every Student Succeeds Act, or ESSA, which requires states to judge schools by non-academic measures as well as test scores.

Meanwhile, issues of race and policing have educators talking about how to foster conversations about social justice in school.

In the wake of police-related killings that rocked the nation, five Memphis teachers talked about how they tackle difficult conversations about race all year long.

School closures made headlines again in Memphis — with more closings likely.

Closing schools has become an annual event as Tennessee’s largest district loses students and funding, and this year was no exception. The shuttering of Carver and Northside high schools brought the total number of district-run school closures to at least 21 since 2012. And more are likely. This month, Shelby County Schools is scheduled to release a facilities analysis that should set the stage for future closures. Superintendent Dorsey Hopson has said the district needs to shed as many as two dozen schools — and 27,000 seats — over the next four years. A Chalkbeat analysis identifies 25 schools at risk.

Exacerbating the challenges of shifting enrollment, families in Foote Homes scrambled to register their children for school as Memphis’ last public housing project prepared to close this month amid a delay in delivering housing vouchers to move elsewhere.

The new school year has officially begun, with the budget approved not a moment too soon for Shelby County Schools.

District leaders that began the budget season facing an $86 million shortfall eventually convinced county commissioners to significantly increase local funding, while also pulling some money from the school system’s reserve funds. The result is a $959 million budget that gives most of the district’s teachers a 3 percent raise and restores funding for positions deemed critical for continued academic progress.

The district also unveiled its first annual report on its growing sector of charter schools.

With charter schools now firmly entrenched in Memphis’ educational landscape, a Shelby County Schools analysis shows a mixed bag of performance, while calling on traditional and charter schools to learn from each other and promising better ways to track quality.

Ten stories you might have missed over the summer (and should read now as a new school year begins)

There is no such thing as time off from covering education. While school doors were shuttered, plenty happened this summer on the Colorado education beat. Here, we’ve compiled stories that we hope prove useful as you ease back into your fall routines.

We’ve got your immunization data right here …

For the second year, Chalkbeat tracked down immunization data for more than 1,200 schools in Colorado’s largest school districts. Our database revealed that Boulder remains a hotspot for the anti-vaccination movement, students in districts with racial and income diversity are more likely to get their shots and nearly half of schools in the database did a better job this year tracking students’ immunization records. Read our news story about the findings, check out these six charts that dig into the numbers and search for school-level data here.

In June, Denver Public Schools’ longtime schools chief returned from a six-month unpaid sabbatical in South America with his family. “It made us appreciate the extraordinary resources we have here,” he said in an interview about his experience.

A milestone for Colorado charter schools on diversity, but not so much on integration

But the University Club has a lovely lunch menu (and squash courts, too)…

What if the State Board of Education held a not-so-public meeting with the education commissioner at a private club downtown to prioritize goals, but didn’t get much of anything accomplished? That happened.

Despite opposition from advocacy groups, Colorado appears headed toward lifting a seven-year ban on diet soda in high schools. The rule change would clear the way for diet soda to be sold in high school vending machines and school stores, though districts could decide not to stock the drinks. We covered the issue before and after the State Board of Education’s initial vote.
